Definitions
- This invention relates to laundry additive products in the form of compositions in water releasable combination with non particulate flexible substrates and is especially concerned with such products in which the composition comprises a peroxyacid bleach precursor.
- the invention relates to such laundry additive products in which the peroxy acid bleach precursor comprises an acyl radical incorporating an alkyl group of narrowly defined chain length attached to a leaving group containing a radical conferring water-solubility.
- peroxy acid bleach precursors in water releasable combination with a non particulate sheet substrate is known in the art, being disclosed in British Patent Nos. 1,586,769 and 2040983.
- peroxybleach precursors Numerous classes of peroxybleach precursors have also been disclosed in which the leaving group contains a radical conferring water solubility.
- One such class is the acyl oxybenzene sulphonates which are disclosed in British Patent Nos. 864,798 and 836,988.
- aliphatic peroxy acids having a range of bleach performance previously thought to be unobtainable under domestic laundry washing conditions can be produced in the wash solution by the reaction of certain types of peroxyacid precursors with alkaline hydrogen peroxide.
- This range of bleaching performance encompasses the bleaching of fugitive dyes in the wash solution, the removal of conventiona.1 bleach sensitive stains such as tea, wine and coffee on fabric and also the removal of accumulated soil stains resulting from incomplete previous washes, the so called 'dingy fabric clean up'.
- the incorporation of the acyl oxybenzene sulphonate into a non-particulate substrate permits the use of the precursor in very finely divided form without an accompanying loss in stability and also assists in improving the rate of peroxyacid generation from the precursor in a wash liquor.
- the present invention therefor provides a detergent additive product comprising
- composition preferably being substantially anhydrous and optionally, including a processing aid
- the precursor has the general formula wherein R is a C S -C '8 alkyl group wherein the longest portion of the linear carbon atom chain extending from and including the carbonyl carbon contains from 6 to 10 carbon atoms, and L is a leaving group the conjugate acid of which has a pKa in the range from 6 to 13.
- R is an alkyl chain containing from 5 to 12 carbon atoms and most preferably is a linear- alkyl group of seven or eight carbon atoms.
- the composition also contains a peroxy acetic acid percursor in an amount sufficient to provide a molar ratio of peroxy acetic acid to Cg ⁇ C io aliphatic peroxy acid of from 10:1 to 1:1.
- the flexible substrate is in the form of a sheet wherein the weight ratio of the precursor to the sheet lies in the range from 10:1 to 1:10.
- peroxyacid bleach precursor defines an organic compound capable of reaction with perhydroxyl ion derived from hydrogen peroxide or an inorganic peroxygen-containing compound in aqueous solution to give an organic peroxy acid having a bleaching performance at least equivalent to that of the hydrogen peroxide or inorganic peroxygen containing compound at a temperature of 70°C and below, under the same condition.
- inorganic peroxy bleach and inorganic persalt are intended to cover salts such as alkali metal perborates, percarbonates, persilicates and perpyrophosphates which produce hydrogen peroxide in aqueous solution rather than compounds such as persulphates and permanganates which produce other peroxy species.
- water-releasable combination is taken to mean a combination capable of being separated by water through solution, dispersion, leaching, softening or melting.
- the invention comprises two components viz, a C s -C, 8 alkyl group-containing acyl bleach precursor in which the longest linear alkyl chain including the carbonyl carbon contains from 6 to 10 carbon atoms, and the non-particulate flexible substrate.
- the acyl group-containing bleach precursor has the general formula where R is a C 5 ⁇ C 18 alkyl group in which the longest portion of the linear carbon atom chain extending from and including the carbonyl carbon contains from 6 to 10 carbon atoms, and L is a leaving group the conjugate acid of which has a pKa in the range from 6 to 13.
- R is a C 5 ⁇ C 12 alkyl group and more preferably is a C 5 ⁇ C 9 linear alkyl group, the most preferred group being a C 8 linear alkyl moiety.
- a leaving group is any group that is displaced from the bleach precursor as a consequence of the nucleophilic attack on the bleach precursor by perhydroxide anion generated by alkaline hydrogen peroxide. This, the perhydrolysis reaction, results in the formation of the percarboxylic acid.
- a group to be a suitable leaving group it must exert an electron withdrawing effect within the precursor molecule as this facilitates the nucleophilic attack by the perhydroxide anion.
- Suitable leaving groups for this purpose have conjugate acid forms, the pKa of which should lie within the range from 6 to 13.
- pKa values above 13 make the electron withdrawal effect so small as to be ineffective in promoting nucleophilic attack by perhydroxy anion, an example of such a leaving group being -OCH 3 .
- pKa values below 6 reflext such a large electron withdrawal effect as to make the molecule reactive to a wide variety of materials including e.g. water. Certain aliphatic anhydrides fall into this class.
- the preferred leaving group L has the formula a) in which Z is H, x is 0, and Y is a sulphonate, carboxylate or dimethyl amine oxide radicals.
- the position of the solubilising group Y on the benzene ring in formula a) is not critical in that o-, m-and p-positions provide operable species. Nevertheless polar and steric factors make the p-substituted material easiest to synthesise and of most value in that its rate of perhydrolysis is fastest.
- leaving group L where Y is a sulphonate radical, the precursor will normally be isolated in the form of its alkali metal salt because of the difficulty of handling the acid form.
- alkyl group R has been expressed as a single chain length material, commercial blends comprising 'cuts' of material having an average in the desired range can also be used.
- alkyl groups may be derived from naturally occurring materials or may be derived synthetically by e.g. OXO or Ziegler processes.
- the selection of the class of precursor for the present invention constitutes a compromise between thermal stability, chemical stability, water solubility and weight effectiveness. Raw material cost and ease of manufacture are also important considerations.
- a conventional synthesis route for acyl oxybenzene sulphonates employs the refluxing for six hours of trifluoroacetic anhydride, sodium phenol sulphonate and the aliphatic carboxylic acid corresponding to the desired peroxy acid.
- the product is recovered by cooling the reaction mixture, precipitating the peroxy acid precursor in a large excess of diethyl ether and filtering off the precipitate.
- An alternative technique employs a two stage reaction in which the aliphatic carboxylic acid is first converted to the anhydride by means of an excess of acetic anhydride, followed by reaction of the recovered acyl anhydride with sodium phenol sulphonate.
- the preferred method of synthesis involves heating n-nonanoyl chloride with sodium phenol- sulphonate at 80-100°C in an aprotic solvent, e.g. dioxane, dichlorethane or toluene, in a current of nitrogen to remove by-product HCI.
- an aprotic solvent e.g. dioxane, dichlorethane or toluene
- the mixture is diluted with acetone or ether and the product is then filtered off.
- Peroxyacids having alkyl groups in the range C Z -C 5 provide approximately the same type of low temperature ( ⁇ 70°C) bleaching capability, viz. removal of oxidisable stains such as tea and wine, as that for the C, alkyl peroxyacid (peroxyacetic acid).
- ⁇ 70°C low temperature
- alkyl peroxyacid peroxyacetic acid
- alkaline hydrogen peroxide solutions including acyl group-containing bleach precursors in which the alkyl group has 10 or more carbon atoms provide little or no removal of tea or wine stains from fabrics at precursor usage levels in excess of 20 ppm. The lack of effect is even more marked in the presence of surfactants.
- C io+ acyl precursors themselves display a degree of surface activity which results in the molecules associating above a certain concentration (the critical micelle concentration or CMC) to form micelles.
- the precursors also tend to form mixed micelles with any other surfactant(s) which may be present.
- the alkyl group of the precursor is believed to align itself in the inner, hydrophobic part of the micelle so that the linkage is not available for attack by the -OOH ion in the aqueous phase.
- C 10+ aliphatic monoperoxy acids are formed from their precursors, they do not provide appreciable stain removal of tea and wine stains although they do bleach oxidisable transient dyes associated with soil deposited and not removed in previous washes.
- This soil-dye interaction causes fabrics which have been subjected to many cycles of usage and washing to become dull and assume a grey tint.
- the accumulated soil tends to be a blend of particulate and greasy materials and the alkyl peroxy acids produced by the preferred C 7 -C a linear acyl oxybenzene sulphonate bleach precursors are particularly effective in removing soil stains of this nature.
- the removal of this accumulated soil-dye staining is sometimes referred to as 'dingy fabric clean up'.
- linear aliphatic peroxyacids in which the alkyl group has from 5 to 9 carbon atoms, more preferably from 6 to 9 carbon atoms and particularly 7 or 8 carbon atoms display a range of bleaching capability and degree of bleaching performance which is surprising. It has been found that the C, and C 8 aliphatic peroxyacids not only give classic oxidisable soil stain removal benefits on fabrics and inhibition of dye transfer via transient dyes in the bulk wash solution similar to those given by peroxyacetic acid, but also provide dingy fabric clean up.
- the amount of the linear C 6 ⁇ C 10 carbon chain-containing bleach precursor applied to the substrate is arranged such that the precursor:substrate ratio is within the range from 30:1 to 1:10, more usually from 10:1 to 1:10 by weight.
- precursor:substrate weight ratios lie within the range from 8:1 to 1:2 and most preferably within the range 5:1 to 1:1.
- the precursor has the maximum surface area i.e. be in finely divided form.
- the particle size will approach impalpability, i.e. individual particles cannot be distinguished from each other by touch which occurs at a particle size 50 micrometers and below.
- the precursor is incorporated on the substrate as a dispersion in a liquid medium, it is preferred that the particle size be reduced before incorporation to less than 200 micrometers maximum preferably less than 100 micrometers maximum.
- the products of the invention may optionally contain any of the organic peroxy acid bleach precursors known in the art.
- a detailed disclosure of such precursors is provided in British Patent Specification No. 2040983.
- blends of linear C 6 ⁇ C 10 acyl oxybenzene sulphonate or carboxylate with peracetic acid precursors are preferred, examples of such peracetic acid precursors including tetra acetyl ethylene diamine, tetra acetyl methylene diamine, tetra acetyl glycoluril, sodium p-acetoxybenzene sulphonate, penta acetyl glucose, octa acetyl lactose.
- the invention also contemplates blends of linear C 6 -C lo carbon chain-containing precursors with e.g. peroxybenzoic and peroxyphthalic acid precursors where different combinations of bleaching properties are required.
- the C 6 ⁇ C 10 acyl oxybenzene sulphonate precursors should be present in an amount to provide a level of at least 2 ppm and preferably at least 5 ppm available oxygen in the wash liquor, in order that the benefit of the C 6 -C lo peroxy acid can be realised.
- the weight ratio of the C 6 ⁇ C 10 acyl oxybenzene sulphonate precursor to the other peroxy acid e.g.
- peracetic acid precursor should be such as to provide a C 6 -C io alkyl peroxy acid:peracetic acid molar ratio in the range from 1:1 to 1:10.
- blends in which the C 6 ⁇ C 10 acyl oxybenzene sulphonate delivers from 5 to 14 ppm available oxygen in the wash liquor are preferred.
- the level of usage of the precursor will naturally be dependent on a number of factors e.g. the size of the fabric load in the machine, the level of bleaching performance desired, the amount of perhydroxyl ion in the wash solution, the bleaching efficacy of the organic peroxy species derived from the precursor and the efficiency of conversion of the precursor into that peroxy species. It is conventional with inorganic peroxy bleaches to provide a level of available oxygen in solution from 50 ppm to 350 ppm by weight for heavy duty laundry purposes.
- a level of available oxygen provided by the organic peroxy compound may lie in the range from 2 ppm to 100 ppm, levels of from 3 ppm to 30 ppm being appropriate under conventional US washing conditions while levels of from 20 ppm to 50 ppm are more commonly used under European washing conditions. This level of available oxygen should be attained within the normal wash cycle time i.e. within 5-25 minutes depending on the particular wash cycle being employed.
- a level of available oxygen requires the deliveryy of from 1 gr to 20 gr of organic peroxy compound precursor assuming quantitative conversion. This figure will increase proportionately with any decrease in the efficiency of conversion.
- a single unit of substrate should be capable of accommodating this level of precursor and any adjuvants and additives that it is necessary to incorporate into the product although the number of units to be used to deliver a given quantity of precursor is a matter of choice.
- the weight of precursor per delivery will lie in the range from 3 to 10 grs, preferably from 4 to 6 grs.
- the second component of the invention in its broadest form, is a non-particulate, flexible substrate with which the acyl oxybenzene sulphonate bleach precursor is in water releasable combination.
- the substrate may itself be water soluble or water insoluble and in the latter case it should possess sufficient structural integrity under the conditions of the wash to be recovered from the machine at the end of the laundry cycle. Structures which are water disintegratable i.e. that break down in aqueous media to insoluble individual fibres or particles are not considered satisfactory for the purposes of the present invention.
- Water soluble materials include certain cellulose ethers, alginates, polyvinyl alcohol and water soluble polyvinyl pyrrolidone polymers, which can be formed into non-woven and woven fibrous structures.
- Suitable water insoluble materials include, but are not restricted to, natural and synthetic fibres, foams, sponges and films.
- the substrate may have any one of a number of physical forms such as sheets, blocks, rings, balls, rods or tubes. Such forms should be amenable to unit usage by the consumer, i.e. they should be capable of addition to the washing liquor in measured amounts, such as individual sheets, blocks or balls and unit lengths of rods or tubes. Certain of these substrate types can also be adapted for single or multiple uses, and can be provided with loadings of organic peroxy acid precursor up to a precursor:substrate ratio of 30:1 by weight.
- One such article comprises a sponge material releasably enclosing enough organic peroxy compound precursor to provide bleaching action during several washing cycles.
- This multi-use article can be made by impregnating a sponge ball or block with about 20 grams of the precursor and any adjuncts therewith. In use, the precursor leaches out through the pores of the sponge into the wash liquor and reacts with the inorganic peroxy bleach.
- Such a filled sponge can be used to treat several loads of fabrics in conventional washing machines, and has the advantage that it can remain in the washer after use.
- a highly preferred product comprises a C s -C 1o linear acyl oxybenzene sulphonate precursor impregnated on a flexible sheet so as to make it compatible with the movement of the fabrics in the washing machine and to facilitate its handling during manufacture of the product.
- the sheet is water pervious i.e. water can pass from one surface of the sheet to the opposite surface and, for film type substrates, perforation of the sheet is desirable.
- the most preferred form of the substrate is a sheet of woven or non-woven fabric or a thin sheet of cellular plastics material.
- Woven fabric sheets can take the form of a plain weave natural or synthetic fibre of low fibre count/unit length, such as is used for surgical dressings, or of the type known as cheese cloth. Loading limitations on sheet type substrates limit the amount, of precursor that can be applied to the sheet namely to a maximum represented by a precursor:sheet weight ratio of about 10:1.
- a very desirable attribute of the laundry additive products of the present invention is that they do not interfere with the mechanical operation of the washing machine into which they are put.
- a high proportion of domestic washing machines are of the rotating perforated drum type in which the perforations extend over the entire peripheral surface. In this type of equipment the drum construction and mode of operation obviates any problem of obstruction to liquid flow in the machine.
- Certain older types of machine utilise an agitator in a stationary vessel provided with a recirculating liquid system. In order to avoid liquid blockage in this machine type it may be necessary to provide slits or perforations in the substrate, particularly if it is in sheet form. Sheet structures of this type are disclosed in McQueary US Patents Nos. 3944694 and 3956556 issued March 16, 1976 and May 11, 1976 respectively.
- suitable materials which can be used as a substrate in the invention herein include, among others, sponges, paper, and woven and non-woven fabrics.

- non-woven cloths are not a part of this invention and being well known in the art, are not described in detail herein.
- such cloths are made by air or water laying processes in which the fibres or filaments are first cut to desired lengths from long strands, passed into a water or air stream, and then deposited onto a screen through which the fibre-laden air or water is passed. The deposited fibres or filaments are then adhesively bonded together, dried, cured and otherwise treated as desired to form the non-woven cloth.
- Non-woven cloths made of polyesters, polyamides, vinyl resins, and other thermoplastic fibres can be bonded, i.e. the fibres are spun out onto a flat surface and bonded (melted) together by heat or by chemical reactions.
- the absorbent properties desired herein are particularly easy to obtain with non-woven cloths and are provided merely by building up the thickness of the cloth, i.e. by super-imposing a plurality of carded webs or mats to a thickness adequate to obtain the necessary absorbent properties, or by allowing a sufficient thickness of the fibres to deposit on the screen.
- Any diameter or denier of the fibre (generally up to about 10 denier (1.1 Tex)) can be used, inasmuch as it is the free space between each fibre that makes the thickness of the cloth directly related to the absorbent capacity of the cloth, and which further makes the non-woven cloth especially suitable for impregnation with a peroxy compound precursor by means of intersectional or capillary action.
- any thickness necessary to obtain the required absorbent capacity can be used.
- binder-resins used in the manufacture of non-woven cloths can provide substrates possessing a variety of desirable traits.
- the absorbent capacity of the cloth can be increased, decreased, or regulated by respectively using a hydrophilic binder-resin, a hydrophobic binder-resin or a mixture thereof in the fibre bonding step.
- the hydrophobic binder-resin when used singly or as the predominant compound of a hydrophobic-hydrophilic mixture, provides non-woven cloths which are especially useful as substrates when the precursor-substrate combinations disclosed herein are used in an automatic washer.
- the substrate herein is a non-woven cloth made from fibres, deposited haphazardly or in random array on the screen, the compositions exhibit excellent strength in all directions and are not prone to tear or separate when used in the washer.

- the fibres are regenerated cellulose, 15 mm in length, 1.5 denier (0.16 Tex), and are lubricated with a similar standard textile lubricant.
- the fibres comprise 70% of the non-woven cloth by weight and are oriented substantially haphazardly; the binder-resin (HA-8) comprises 30% by weight of the cloth.
- the substrate is 101.5 micrometers (4 mils) thick, and it has a basis weight of 29 g/m 2 .

- apertured fabrics for the purposes of the invention have from 10 to 20 apertures/cm2, preferably 12 to 18 apertures/cm2.
- the size and shape of the substrate sheet is a matter of choice and is determined principally by factors associated with the convenience of its use. Thus the sheet should not be so small as to become trapped in the crevicas of the machine or the clothes being washed or so large as to be awkward to package and dispense from the container in which it is sold.
- sheets ranging in plan area from 130 cm 2 to 1300 cm 2 are acceptable, the preferred area lying in the range of from 520 cm 2 to 780 cm 2 .
- one or more other materials can be applied to the substrate either separately or together with the precursor.

- Individual optional components can be incorporated in amounts up to those corresponding to component:substrate weight ratios of 20:1. However, for processing and product aesthetics reasons, the total weight of optional components per sheet is normally held to a maximum of 12 times the sheet weight, and ideally is less than 7 times the sheet weight, individual components being present at no more than 4 times the sheet weight.

- the processing aid does not have any other function in the product such as a component of the surfactant mixture, its level of incorporation will be such that the precursor:processing aid weight ratio will be in the range from 20:1 to 1:3, the latter value being for economic reasons.
- the weight ratio of precursor:processing aid can be as low as 1:10 where the processing aid has other functional properties such as surfactancy.
- the organic adjuvant can serve as a release aid that assists in releasing the precursors from the substrate upon addition of the product to a wash liquor.

- Application of the precursor can be carried out in any convenient manner, and many methods are known in the art.
- the preferred acyloxybenzene sulphonate or carboxylate precursors are solid at temperatures in excess of 150°C, one form of application is by solution in organic solvents which are volatilised after application, while another employs a slurry or suspension of the finely divided solid in water or other liquid media.
- compositions in accordance with the invention are substantially anhydrous and thus incorporation on the substrate is best accomplished by utilisation of a non aqueous liquid medium.
- a highly preferred embodiment of the invention utilises a processing aid and/or other optional ingredients in molten form as the liquid medium in which the finely divided precursor is dispersed.
- the substrate comprises a non-sheet like reticulated foam article
- a liquid medium incorporating the dispersed precursor either alone or with other components of the formulation
- a compatible non-hygroscopic material of higher melting point such as the processing aids hereinbefore described to provide a waxy solid in which the surfactant is present in the form of a solid solution and/or as a dispersed phase.
- the melting point range and waxy nature of polyethylene glycols of molecular weight 5 4000 make them useful for this purpose.
- nonionic surfactants form components of the composition
- their physical properties may permit their use as, or as part of, a liquid medium in which the precursor and other solid components are incorporated.
- the nonionic surfactant is a solid at normal temperature but is molten at a temperature less than 100°C, preferably less than 80°C
- the surfactant can be used as the sole vehicle for incorporating other non liquid components into the substrate.
- Alcohols having high levels of ethoxylation such as Tallow alcohol (E z6+ ) and C,4--C,5 primary alcohol E 15 are examples of such materials.
- materials reactive towards the C 6 -C la linear carbon chain-containing bleach precursor can be incorporated in the additive products of the present invention provided that the precursor and the reactive material are spatially separated from one another.
- Inorganic peroxygen bleaches which either contain water or hydrogen peroxide in hydrogen bonded form, such as sodium perborate tetrahydrate, sodium percarbonate, sodium persilicate or sodium perpyrophosphate, and also urea- hydrogen peroxide addition products, are materials which are sufficiently reactive to require this spatial separation.
- the precursor and the inorganic peroxygen bleach are incorporated in physically separate locations, on the same substrate
- a convenient method of application is the deposition of the respective melts, suspensions or solutions as discrete bands of material on the substrate.
- the bleach is applied as a dispersion of solid particles in a molten processing aid (as hereinbefore described) at a temperature in the range from 40° to 60°C.
- molten processing aid as hereinbefore described
- bleach: substrate weight ratios of up to 15:1 can be obtained. This level of loading is attainable with cellular substrates but substrates of fibrous character are limited in practice to weight ratios of 5:1.
- loading limitations imposed by the substrate surface area required for the incorporation of the precursor may limit the amount of bleach to less than 3:1.
- composition is minimised and product aesthetics such as feel are enhanced during both manufacture and storage if the water content of the composition is mimimised.
- the composition is substantially anhydrous but more usually the water content is in the range from 5-8% by weight of the additive product.
- compositions containing sodium perborate monohydrate in intimate mixture with the other components it has been found that any halide anions present in the mixture react with the bleach when the mixture is heated.
- chloride salts must be excluded from such mixtures and any cationic surfactants present must be in the form of a non-oxidisable. salt such as the methosulphate.
- the substrate is impregnated, it is believed that the surfaces of the pores or fibres making up the substrate are themselves coated and it is a highly desirable aspect of the substrate that it permits an extensive coating of the peroxy compound precursor to be formed.
- the term 'coating' connotes the adjoining of one substrate to the surface of another; 'impregnation' is intended to mean the permeation of the entire substrate structure, internally as well as externally.
- One factor affecting a given substrate's absorbent capacity is its free space. Accordingly, when a precursor is applied to an absorbent substrate, it penetrates into the free space, hence, the substrate is deemed impregnated.
- a substrate of low absorbency such as one-ply kraft or bond paper
- a substrate is; therefore, termed "dense".
- a small portion of the precursor penetrates into the limited free space available in a dense substrate, a rather substantial balance of the precursor does not penetrate and remains on the surface of the substrate so that it is deemed a coating.
- the precursor is applied to absorbent paper or non-woven cloth by a method generally known as padding.
- the precursor is preferably applied from a liquid to the substrate and precursors which are normally solid at room temperature should first be melted, dissolved in solvent or suspended in a liquid application medium.
- the precursor-containing liquid is placed into a pan or trough which can be heated, if necessary, to maintain the contents in liquid form. Any optional ingredients are then added to the pan or trough.
- a roll of absorbent substrate is then set up on an apparatus so that it can unroll freely. As the substrate unrolls, it travels downwardly and, submersed, passes through the pan or trough containing the precursor at a slow enough speed to allow sufficient impregnation.
- the absorbent substrate then travels, at the same speed, upwardly and through a pair of rollers which squeeze off excess bath liquid.
- the impregnated substrate is then cooled to room temperature, after which it can be folded, cut or perforated at uniform lengths, and subsequently packaged and/or used.
- rollers used resemble "squeeze rolls" used by those in the paper and paper-making art; they can be made of hard rubber or steel.
- the rollers are adjustable, so that the orifice between their respective surfaces can be regulated to control the amount of the precursor liquid on the substrate.
- the precursor in liquid form is sprayed onto absorbent substrate as it unrolls.
- the unrolled substrate web is arranged to slide over the spray nozzle which comprises a horizontally disposed tube formed with a slit extending along its top surface.
- the molten slurry of organic peroxy compound precursor and any additives mixed herewith is forced through the slit into the substrate and the excess liquid is then squeezed off by the use of squeeze rollers.
- a melt temperature in the range of 40°-80°C, preferably 45° ⁇ 65°C is used and the molten material should have a viscosity of less than 5 Pa.Sec at 50°C, preferably no more than 0.5 Pa.Sec.
- the precursor(s) dissolved or dispersed in a molten processing aid are held in a trough formed by the nip of two horizontal rollers arranged side by side and rotating in opposite directions such that the nip is formed by surfaces having approximately the same velocity in a downward direction.
- Molten material is spread on one of the rolls and transferred to a continuous web of substrate whose speed is the same as that of the roll and which contacts the roll over a limited length of its periphery/The impregnated substrate is then contacted by a smoothing and spreading roll having a direction of rotation such that its contact surface is moving in the opposite direction to that of the substrate.
- This variation additionally involves the use of metal rollers which can be heated to maintain the precursor in the liquid phase.
- a further method involves separately treating a desired number of the individual plies of a multi-ply paper and subsequently adhesively joining the plies with a known adhesive-joiner compound; this provides a composition which can be treated on one of its outer sides, yet contains several other plies, each of which is treated on both sides.
- a mixture of the precursor and any added materials is applied to the substrate as a dispersion in a molten material, usually a ⁇ processing aid such as polyethyl glycol, but frequently including an ethoxylated nonionic surfactant.
- a ⁇ processing aid such as polyethyl glycol, but frequently including an ethoxylated nonionic surfactant.
- the additive products of the present invention can be introduced into the washing liquor at a point in the washing process where formation of an organic peroxy bleaching species is of most value.
- optimum results are obtained, irrespective of the washing cycle being employed, when the additive products of the present invention are fed into the machine at the same time as the fabric load.
- addition of the additive product at the beginning of the main wash cycle is preferred.
- Sodium nonanoyl oxybenzene sulphonate was prepared by reacting C 9 alkyl fatty acid with trifluoroacetic anhydride and sodium phenol sulphonate for six hours, precipitating the sodium salt from an aqueous alcoholic solution and washing and drying the precipitated salt.
- the sodium nonanoyl oxybenzene sulphonate crystals are passed through a sieve of mesh size 350 micrometers and redispersed in methanol to form a 25% suspension before being subjected to wet milling using a Fryma Colloid Mill, Model MK95R/MZ 80R (made by M. M. Process Equipment Ltd, of M. M.
- the milled suspension is then applied to a hydrophilic, reticulated polyurethane foam sheet substrate.
- the substrate comprises a 3 mm thick sheet of "Hydrofoam” (RTM) having a density of 0.0036 g/ cm 2 and a cell count of 25-30 per cm, the sheet size being 36 x 23 cm and the basis weight being 0.9 g/ sheet.
- the precursor is applied by immersing the sheet in the suspension to saturate it, excess liquid being subsequently removed by passing the sheet through a nip formed by a pair of rollers.
- the methyl alcohol vehicle is then evaporated from the sheet to leave a product containing 4.5 g sodium nonanoyl oxybenzene sulphonate.
- compositions of Product A comprises 5 g TAED, designed to provide 35 ppm of available oxygen in a 20 litre wash solution assuming theoretical conversion of the precursor, while the composition of Product B comprises 6.3 g NOBS designed to provide 15 ppm available oxygen on the same basis.
- the additive products are compared by adding a sheet to a commercial inorganic oxygen bleach- containing detergent and carrying out bleaching performance tests on tea- and wine-stained cotton and polyester-cotton swatches in a washing machine containing a load of clean fabrics as 'ballast'.
- the sheet is added with the load while the detergent is added via the dispenser. Tests are also carried out using the commercial detergent alone to provide a base line of bleaching performance.
- the commercial detergent has the following formula
- compositions were arranged so that one sheet in a 20 litre wash solution would provide 35 ppm available oxygen from the peracid present assuming theoretical conversion of the precursor(s), Composition C providing 35 ppm from the peracetic acid, Composition D providing 30 ppm from the peracetic acid and 5 ppm from the Cg peroxyacid, and Composition E providing 25 ppm from the peracetic acid and 10 ppm from the Cg peroxyacid.
- the substrate in each instance was a square patterned apertured non-woven sheet, of size 23 x 35 cm and basis weight 2.8 g, formed of 100% unbleached crimped rayon fibres (80% fibre, 20% polyacrylate binder).
- the products were made in each case by forming a melt of the PEG and A 42E7 at approximately 80°C, dispersing the other components (except the perfume) therein and applying the resultant slurry to the substrate from an applicator roll with which the substrate was brought into contact. Additional rolls were used to spread the slurry before it was cooled to ambient temperature to solidify the composition. Perfume was then sprayed on to the impregnated substrate to produce the final product.
- the performance of the products was assessed by means of bleachable stain removal (tea, wine) on cotton and polyester-cotton fabric tracers, and also by means of the cleaning of accumulated soil stains on a woven cotton roller towel sample, the tracers and the sample being included in each load.
- the H 2 0 2 clathrate was added as a dry powder to the molten mixture of PEG 8000 and Dobanol 45E7, together with the other components.
- This additive product had a 1:1 molar ratio of NOBS to H 2 0 2 and was designed such that a single sheet would provide 3 ppm available oxygen under US washing conditions (60 litres wash liquor volume, detergent co-product (US Tide®) contains no peroxygen bleach).
- Example 4 was repeated except that 3.6 g of sodium perborate monohydrate was added in place of the H 2 0 2 clathrate.
